Fortunately, Aegle did not take Zari's very reasonable proclamation that he could find out who either of them were as a challenge. Fortunately for Aegle and Lily at least. If Aegle's mouth had succeeded in overriding her limited common sense, there was no telling the damage she might have done before finally being shut up. Instead, the orange haired girl let herself enjoy the satisfaction of being appointed Lily's guide. Zari almost certainly would have done a better job showing the new student around, but Aegle somehow managed to completely overlook that point, and merely considered Lily's acceptance of her offer as the personal triumph it most assuredly was. 

When the focus of the conversation shifted away from her though, Aegle was left looking rather uncertain. At his explanation for his precise topic of study, Aegle took a renewed interest in Zari, and was surprised she didn't already know who he was. Aura and combat were her specialties, after all. The fact that she would miss something so relevant to her interests really shouldn't have come as that great a surprise though. Aegle could successfully overlook a cliff, even after stepping right off of it. 

"M'names Aegle..." The smaller girl offered eventually, after Lily provided her own introduction. She hadn't really felt that compelled to introduce herself, at least not beyond general good manners which seldom meant much to her anyway, but she wanted to feel like she was somehow involved in the conversation again. 
"and you can keep your tea. M'not really supposed to have caffeine..." Tea was an old people drink anyway. Aegle might have said more on the subject, but her attention was wandering again. Something that Lily had said caught her attention. It was only as Zari was giving her the offered cup of tea that it clicked.
"Wait, your name's Wilde?" She asked, her smile renewed with laughter just barely restrained in her jovial tone. As she thought more about it, her grin grew wider and wider, and a couple of quiet snickers managed to escape her lip. She might have said more on that subject too, but there was a real risk that the next time she opened her mouth, laughter would explode out of her like air from a deflating balloon. Rather acutely aware of that risk, Aegle covered her mouth in a vain attempt to repress her mirth. The idea of a Faunus named 'Wilde' was simply too funny for her to handle, and it didn't really occur to her how Lily's family, or Lily in particular might have happened upon such a name. Though it wasn't the case in this particular instance, there were surely a few Faunus Wildes in Remnant who'd had the name forced on them by unimaginative institutional prejudice. Aegle remained oblivious to that fact, however. Just as she remained oblivious to the fact that Lily's last name was as appropriate as her own was ironic.
"That's awesome~" she finally managed, somehow keeping herself from breaking out in a gale of laughter.

While Zari wouldn't call the girl strange, he did find parts of her behavior questionable. After showing she didn't know what a handshake was, the man began to paint a picture of Lily's upbringing. It was clear that she didn't know many of the common courtesys people used. A number of students have come to Vytal from places outside of the Kingdoms. Small villages, tribes, or towns that were just not properly mapped and nor visited often. That would explain her behavior. The ignorance of courtesy and the anxiety of being in crowds. Though he was forced to take a frown when she called him a warrior. He wanted to correct her, but that could lead to trouble with Aegle around. The girl could try to dig deep when he said he wasn't a warrior. Not fully anyway.

Mimicking her movements, Zari also bowed his head with a smile. "I am happy to have you as a student. I will be sure to work you to the bone. Make sure you come to me if you need anything. I might not be my master, but I did train as a Cela Monk. I'll get you two to new heights." He addressed them both, before he unscrewed the top of his thermos. Using the top as a cup, he poured the remainder of his tea into it and offered the drink to Lily. Turning to Aegle, Zari shifted as he glanced the girl up and down. Currently the girl was a mystery to him. Both were. He'd have to learn about their fighting capabilities soon in order to properly train them. "No rest for the wicked." He muttered before turning to see the new arrival.

"Oh. Good day to you Young Ara Eisold." Zari placed a hand behind his back. "Just making my rounds and found our new student a little worried. Suppose she will be fine in time." Zari offered the three girls a faint and forced smile. "But might I ask what you are doing here, my dear?" Zari would lift his hand and gesture to Ara's current wardrobe. "Off to...soak in the sun...I guess is the phrase?"

"Oh hey, it's the silver eyed girl." Aegle, who was feeling increasingly marginalized from her introductions to Lily, piped pleasantly when she spied Ara's approach. If the older girl hadn't recognized her distinctive orange fashion sense, she certainly would have recognized Aegle's shrill and loud voice. Her enthusiasm dwindled slightly when Ara's attention inevitably focused on Lily though. It wasn't that Aegle didn't appreciate the novelty of meeting a new person, it was just that she hadn't really seen Ara since the trip to Legion and that she'd thought now might be an opportunity to catch up. She might have reached some conclusions about their relationship following the mission with Aisio which were not wholly well founded. After all, Aegle considered everyone she met a friend, even when those people openly despised her company.

Though Aegle wasn't nearly introspective enough to feel as though she was being left out, the sense that she wasn't wholly involved in the conversation unfolding before her. It was an sense which grew even more acute as both Ara and Lily introduced themselves. Aegle did note Lily once again held her hand out in a weird, not quite handshake way, and briefly wondered if that was some sorta faunus custom or something. Wondering why Faunus might not shake hands like regular people briefly distracted her enough that she was actually a little surprised when she found Lily was addressing her again.
"I didn't say I didn't want any..." Aegle corrected quietly as her expression transitioned from mild surprise to slightly brooding, like she was on the edge of throwing a little sulk. "Like I said, s'just that I'm not s'posed to have caffeine." The little shrug she affected following that clarification gave punctuation to her words. She didn't want to discuss the specific reasons she wasn't allowed caffeine, and the openly sulky demeanor she'd adopted made that fact quite evident. 
"S'an old people drink anyway..." She added in a somewhat quieter tone, as she shot Zari a glance which left no doubt as to whom she was referring. Though she did have a keen desire to improve and the professor happened to teach her two strongest fields, she had yet to forget his threat to put her in detention. All the good will that might have come from him being a potential trainer couldn't quite overcome the possibility that he might have prevented her own private training. She also wasn't sure who he thought he was calling wicked, and was more than a little put off by the implication.

Aegle shifted her attention away from Zari and over to Ara once again, and her smile abruptly reappeared, like she had thrown a switch somewhere in the back of her mind.
"I'm gonna show Lily around." She told the silver eyed girl eagerly, "D'ya wanna join us?" While Zari had made the, not difficult, connection between Ara's outfit and a bit of baking in the sun, Aegle had evidently not. She flashed Ara her too-wide smile in apparent eagerness for the older girl to agree. Then, as if she thought it might sway Ara's decision, Aegle added, "I was gonna take her to the cafeteria first~"
